Spam Control Information

St. Lawrence University uses a combination of real-time block lists (RBL) and Sophos PureMessage to help reduce the amount of unwanted e-mail (spam) that reaches campus. Users have the ability to administer their personal anti-spam preferences from the Sophos PureMessage web interface.

Anti-spam Administration:

Users can perform a variety of administrative functions from the Sophos PureMessage web interface at: http://spam.stlawu.edu/. These options include the ability to:

• maintain an individual blocklist/whitelist
• view/release quarantined messages
• subscribe to daily notifications of quarantined messages
• disable all spam checking for your email account

For detailed instructions on performing any of these operations, use the help link available within the web interface.

Spam Identification Rules:

Spam messages are identified as follows:

1. Messages with a very high probability of being spam are discarded. These are messages with a spam probability higher than 90%, or well known spam sources as identified by a real-time block list.
   
2. Messages with a high probability of being spam (50%-90%) are quarantined. Quarantined messages can be viewed and released via the administrative interface at http://spam.stlawu.edu/, or from a link in a quarantine notification message.
